For purposes of computing the deficiency of earnings available to cover fixed charges, fixed charges represent interest expense, the portion of operating lease rental expense that is considered by us to be representative of interest and amortization of discount related to indebtedness; earnings are defined as net loss from continuing operations before income taxes plus fixed charges; deficiency of earnings consists of loss before income taxes. Historically we have incurred no fixed costs.
